Section 3 - Hazards Identification
Emergency Overview
Appearance: Clear, colorless to light tan liquid
Danger! Corrosive. Causes severe eye, skin, respiratory and digestive tract burns. May cause
liver and kidney damage. Reacts violently with water and many other substances. May cause
methemoglobinemia.
Target Organs: Kidneys, central nervous system, liver, red blood cells, bladder, eyes, skin, lungs,
teeth.
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury, permanent corneal opacification, and
blindness.
Skin:
Causes severe burns. The severity of injury depends on the duration of exposure. May cause skin
sensitization.

Material Safety Data Sheet
Diphenylamine, 1% w/v in Sulfuric Acid
Ingestion:
Causes gastrointestinal tract burns. May cause severe and permanent damage to the digestive tract.
Methemoglobinemia is characterized by dizziness, drowsiness, headache, shortness of breath,
cyanosis, rapid heart rate, and chocolate brown-colored blood.
Inhalation:
Causes respiratory tract irritation and burns. May cause methemoglobinemia, cyanosis,
convulsions, tachycardia, dyspnea, and death. May cause adverse central nervous system effects,
including headache, convulsions, and possible death. May cause bladder injury and hypertension.
Inhalation of sulfuric acid mists causes laryngeal cancer.
Chronic:
Prolonged or repeated skin contact causes dermatitis in skin and eyes. Adverse reproductive effects
have been reported in animals. Prolonged or repeated inhalation may cause nosebleeds, nasal
congestion, erosion of the teeth, perforation of the nasal septum, chest pain, and bronchitis.
Occupational exposure to strong inorganic mists containing sulfuric acid is carcinogenic to humans.
Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids
until no evidence of chemical remains. Get medical aid at once. Cover burns with loose sterile nonmedicated bandages.
Skin:
Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes.
Remove contaminated clothing and shoes. Cover burns with a dry sterile bandage (secure, not tight).
Ingestion:
Do NOT induce vomiting. Get medical aid at once. Give conscious victim large quantities of water
to dilute acid. Give oxygen if respiration is depressed.
Inhalation:
Give artificial respiration if necessary. Get medical aid. Keep victim warm, at rest. Move victim to
fresh air.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
Sulfuric acid is not flammable, but reacts violently and exothermically with water, metals, and some
organic materials. Move container if possible; cool with fog or spray. Do not scatter contents with
excess water. Do not get water inside containers.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.
Autoignition Temperature:
No information found.
Flash Point:
No information found.
